FIELD OF THE INVENTION

This invention relates to pyrrolotriazine compounds, more particularly,to cycloalkyl, heterocyclo and heteroaryl pyrrolotriazine anilinecompounds useful for treating p38 kinase-associated conditions. Theinvention further pertains to pharmaceutical compositions containing atleast one compound according to the invention useful for treating p38kinase-associated conditions and methods of inhibiting the activity ofp38 kinase in a mammal.

BACKGROUND OF THE INVENTION

A large number of cytokines participate in the inflammatory response,including IL-1, IL-6, IL-8 and TNF-α. Overproduction of cytokines suchas IL-1 and TNF-α are implicated in a wide variety of diseases,including inflammatory bowel disease, rheumatoid arthritis, psoriasis,multiple sclerosis, endotoxin shock, osteoporosis, Alzheimer's disease,and congestive heart failure, among others [Henry et al., Drugs Fut.,24:1345-1354 (1999); Salituro et al., Curr. Med. Chem., 6:807-823(1999)]. Evidence in human patients indicates that protein antagonistsof cytokines are effective in treating chronic inflammatory diseases,such as, for example, monoclonal antibody to TNF-α (Enbrel) [Rankin etal., Br. J. Rheumatol., 34:334-342 (1995)], and soluble TNF-αreceptor-Fc fusion protein (Etanercept) [Moreland et al., Ann. Intern.Med., 130:478-486 (1999)]

The biosynthesis of TNF-α occurs in many cell types in response to anexternal stimulus, such as, for example, a mitogen, an infectiousorganism, or trauma. Important mediators of TNF-α production are themitogen-activated protein (MAP) kinases, and in particular, p38 kinase.These kinases are activated in response to various stress stimuli,including but not limited to proinflammatory cytokines, endotoxin,ultraviolet light, and osmotic shock. Activation of p38 requires dualphosphorylation by upstream MAP kinase kinases (MKK3 and MKK6) onthreonine and tyrosine within a Thr-Gly-Tyr motif characteristic of p38isozymes.

There are four known isoforms of p38, i.e., p38-α, p38β, p38γ, and p38δ.The α and β isoforms are expressed in inflammatory cells and are keymediators of TNF-αproduction. Inhibiting the p38α and β enzymes in cellsresults in reduced levels of TNF-α expression. Also, administering p38αand β inhibitors in animal models of inflammatory disease has proventhat such inhibitors are effective in treating those diseases.Accordingly, the p38 enzymes serve an important role in inflammatoryprocesses mediated by IL-1 and TNF-α.

The term “aralkyl” refers to an aryl group bonded directly through analkyl group, such as benzyl, wherein the alkyl group may be branched orstraight chain. In the case of a “substituted aralkyl,” the alkylportion of the group besides being branched or straight chain, may besubstituted as recited above for substituted alkyl groups and/or thearyl portion may be substituted as recited herein for aryl. Thus, theterm “optionally substituted benzyl” refers to the group

The fused ringscompleting the bicyclic and tricyclic groups may contain only carbonatoms and may be saturated, partially saturated, or unsaturated. Thenitrogen and sulfur atoms may optionally be oxidized and the nitrogenatoms may optionally be quaternized. Heteroaryl groups which arebicyclic or tricyclic must include at least one fully aromatic ring butthe other fused ring or rings may be aromatic or non-aromatic.

Unless otherwise indicated, when reference is made to aspecifically-named aryl (e.g., phenyl), cycloalkyl (e.g., cyclohexyl),heterocyclo (e.g., pyrrolidinyl) or heteroaryl (e.g., indolyl), thereference is intended to include rings having 0 to 3, preferably 0-2,substituents selected from those recited above for the aryl, cycloalkyl,heterocyclo and/or heteroaryl groups, as appropriate. Additionally, whenreference is made to a specific heteroaryl or heterocyclo group, thereference is intended to include those systems having the maximum numberof non-cumulative double bonds or less than the maximum number of doublebonds. Thus, for example, the term “isoquinoline” refers to isoquinolineand tetrahydroisoquinoline.

Additionally, it should be understood that one skilled in the field maymake appropriate selections for the substituents for the aryl,cycloalkyl, heterocyclo, and heteroaryl groups to provide stablecompounds and compounds useful as pharmaceutically-acceptable compoundsand/or intermediate compounds useful in makingpharmaceutically-acceptable compounds. Thus, for example, in compoundsof formula (I), when B is a cyclopropyl ring, preferably the ring has nomore than two substituents, and preferably said substituents do notcomprise nitro (NO₂), more than one cyano group, or three halogengroups. Similarly, when m is 3, preferably R₆, the substituents on thephenyl ring A, are not all nitro, and so forth. The term “heteroatoms”shall include oxygen, sulfur and nitrogen.

The term “haloalkyl” means an alkyl having one or more halosubstituents.

The term “perfluoromethyl” means a methyl group substituted by one, two,or three fluoro atoms, i.e., CH₂F, CHF₂ and CF₃. The term“perfluoroalkyl” means an alkyl group having from one to five fluoroatoms, such as pentafluoroethyl.

The term “haloalkoxy” means an alkoxy group having one or more halosubstituents. For example, “haloalkoxy” includes —OCF₃.

The term “carbocyclic” means a saturated or unsaturated monocyclic orbicyclic ring in which all atoms of all rings are carbon. Thus, the termincludes cycloalkyl and aryl rings.

UTILITY

The compounds of the invention are selective inhibitors of p38 kinaseactivity, and in particular, isoforms p38α and p38β. Accordingly,compounds of formula (I) have utility in treating conditions associatedwith p38 kinase activity. Such conditions include diseases in whichcytokine levels are modulated as a consequence of intracellularsignaling via p38, and in particular, diseases that are associated withan overproduction of cytokines IL-1, IL-4, IL-8, and TNF-α. As usedherein, the terms “treating” or “treatment” encompass either or bothresponsive and prophylaxis measures, e.g., measures designed to inhibitor delay the onset of the disease or disorder, achieve a full or partialreduction of the symptoms or disease state, and/or to alleviate,ameliorate, lessen, or cure the disease or disorder and/or its symptoms.When reference is made herein to inhibition of “p-38α/β kinase,” thismeans that either p38α and/or p38β kinase are inhibited. Thus, referenceto an IC₅₀ value for inhibiting p-38α/β kinase means that the compoundhas such effectiveness for inhibiting at least one of, or both of, p38αand p38β kinases.

In view of their activity as inhibitors of p-38α/β kinase, compounds ofFormula (I) are useful in treating p-38 associated conditions including,but not limited to, inflammatory diseases, autoimmune diseases,destructive bone disorders, proliferative disorders, angiogenicdisorders, infectious diseases, neurodegenerative diseases, and viraldiseases.

More particularly, the specific conditions or diseases that may betreated with the inventive compounds include, without limitation,pancreatitis (acute or chronic), asthma, allergies, adult respiratorydistress syndrome, chronic obstructive pulmonary disease,glomerulonephritis, rheumatoid arthritis, systemic lupus erythematosis,scleroderma, chronic thyroiditis, Grave's disease, autoimmune gastritis,diabetes, autoimmune hemolytic anemia, autoimmune neutropenia,thrombocytopenia, atopic dermatitis, chronic active hepatitis,myasthenia gravis, multiple sclerosis, inflammatory bowel disease,ulcerative colitis, Crohn's disease, psoriasis, graft vs. host disease,inflammatory reaction induced by endotoxin, tuberculosis,atherosclerosis, muscle degeneration, cachexia, psoriatic arthritis,Reiter's syndrome, gout, traumatic arthritis, rubella arthritis, acutesynovitis, pancreatic β-cell disease; diseases characterized by massiveneutrophil infiltration; rheumatoid spondylitis, gouty arthritis andother arthritic conditions, cerebral malaria, chronic pulmonaryinflammatory disease, silicosis, pulmonary sarcoisosis, bone resorptiondisease, allograft rejections, fever and myalgias due to infection,cachexia secondary to infection, meloid formation, scar tissueformation, ulcerative colitis, pyresis, influenza, osteoporosis,osteoarthritis and multiple myeloma-related bone disorder, acutemyelogenous leukemia, chronic myelogenous leukemia, metastatic melanoma,Kaposi's sarcoma, multiple myeloma, sepsis, septic shock, andShigellosis; Alzheimer's disease, Parkinson's disease, cerebralischernias or neurodegenerative disease caused by traumatic injury;angiogenic disorders including solid tumors, ocular neovasculization,and infantile haemangiomas; viral diseases including acute hepatitisinfection (including hepatitis A, hepatitis B and hepatitis C), HIVinfection and CMV retinitis, AIDS, ARC or malignancy, and herpes;stroke, myocardial ischemia, ischemia in stroke heart attacks, organhyposia, vascular hyperplasia, cardiac and renal reperfusion injury,thrombosis, cardiac hypertrophy, thrombin-induced platelet aggregation,endotoxemia and/or toxic shock syndrome, and conditions associated withprostaglandin endoperoxidase syndase-2.

In addition, p38 inhibitors of this invention inhibit the expression ofinducible pro-inflammatory proteins such as prostaglandin endoperoxidesynthase-2 (PGHS-2), also referred to as cyclooxygenase-2 (COX-2).Accordingly, additional p38-associated conditions include edema,analgesia, fever and pain, such as neuromuscular pain, headache, paincaused by cancer, dental pain and arthritis pain. The inventivecompounds also may be used to treat veterinary viral infections, such aslentivirus infections, including, but not limited to equine infectiousanemia virus; or retro virus infections, including felineimmunodeficiency virus, bovine immunodeficiency virus, and canineimmunodeficiency virus.

When the terms “p38 associated condition” or “p38 associated disease ordisorder” are used herein, each is intended to encompass all of theconditions identified above as if repeated at length, as well as anyother condition that is affected by p38 kinase activity.

The present invention thus provides methods for treating suchconditions, comprising administering to a subject in need thereof aneffective amount of at least one compound of Formula (I) or a saltthereof. The methods of treating p38 kinase-associated conditions maycomprise administering compounds of Formula (I) alone or in combinationwith each other and/or other suitable therapeutic agents useful intreating such conditions. Exemplary of such other therapeutic agentsinclude corticosteroids, rolipram, calphostin, CSAIDs, 4-substitutedimidazo[1,2-A]quinoxalines as disclosed in U.S. Pat. No. 4,200,750;Interleukin-10, glucocorticoids, salicylates, nitric oxide, and otherimmunosuppressants; nuclear translocation inhibitors, such asdeoxyspergualin (DSG); non-steroidal antiinflammatory drugs (NSAIDs)such as ibuprofen, celecoxib and rofecoxib; steroids such as prednisoneor dexamethasone; antiviral agents such as abacavir; antiproliferativeagents such as methotrexate, leflunomide, FK506 (tacrolimus, Prograf);cytotoxic drugs such as azathiprine and cyclophosphamide; TNF-αinhibitors such as tenidap, anti-TNF antibodies or soluble TNF receptor,and rapamycin (sirolimus or Rapamune) or derivatives thereof.

The above other therapeutic agents, when employed in combination withthe compounds of the present invention, may be used, for example, inthose amounts indicated in the Physicians' Desk Reference (PDR) or asotherwise determined by one of ordinary skill in the art. In the methodsof the present invention, such other therapeutic agent(s) may beadministered prior to, simultaneously with, or following theadministration of the inventive compounds.

Biological Assays Generation of p38 Kinases

cDNAs of human p38α, β and γ isozymes were cloned by PCR. These cDNAswere subcloned in the pGEX expression vector (Pharmacia). GST-p38 fusionprotein was expressed in E. Coli and purified from bacterial pellets byaffinity chromatography using glutathione agarose. p38 fusion proteinwas activated by incubating with constitutively active MKK6. Active p38was separated from MKK6 by affinity chromatography. Constitutivelyactive MKK6 was generated according to Raingeaud et al. [Mol. Cell.Biol., 1247-1255 (1996)].

TNF-αProduction by UPS-Stimulated PBMCs

Heparinized human whole blood was obtained from healthy volunteers.Peripheral blood mononuclear cells (PBMCs) were purified from humanwhole blood by Ficoll-Hypaque density gradient centrifugation andresuspended at a concentration of 5×10⁶/ml in assay medium (RPMI mediumcontaining 10% fetal bovine serum). 50 ul of cell suspension wasincubated with 50 ul of test compound (4× concentration in assay mediumcontaining 0.2% DMSO) in 96-well tissue culture plates for 5 minutes atRT. 100 ul of LPS (200 ng/ml stock) was then added to the cellsuspension and the plate was incubated for 6 hours at 37° C. Followingincubation, the culture medium was collected and stored at −20° C. TNF-αconcentration in the medium was quantified using a standard ELISA kit(Pharmingen-San Diego, Calif.). Concentrations of TNF-α, and IC₅₀ valuesfor test compounds (concentration of compound that inhibitedLPS-stimulated TNF-α production by 50%) were calculated by linearregression analysis.

p38 Assay

The assays were performed in V-bottomed 96-well plates. The final assayvolume was 60 μl prepared from three 20 μl additions of enzyme,substrates (MBP and ATP) and test compounds in assay buffer (50 mM TrispH 7.5, 10 mM MgCl₂, 50 mM NaCl and 1 mM DTT). Bacterially expressed,activated p38 was pre-incubated with test compounds for 10 min prior toinitiation of reaction with substrates. The reaction was incubated at25° C. for 45 min. and terminated by adding 5 μl of 0.5 M EDTA to eachsample. The reaction mixture was aspirated onto a pre-wet filiermatusing a Skatron Micro96 Cell Harvester (Skatron, Inc.), then washed withPBS. The filtermat was then dried in a microwave oven for 1 min.,treated with MeltilLex A scintillation wax (Wallac), and counted on aMicrobeta scintillation counter Model 1450 (Wallac) Inhibition data wereanalyzed by nonlinear least-squares regression using Prizm(GraphPadSoftware). The final concentration of reagents in the assaysare ATP, 1 μM; [γ-³³P]ATP, 3 nM; MBP (Sigma, #M1891), 2 μg/well; p38, 10nM; and DMSO, 0.3%.

TNF-α Production by LPS-Stimulated Mice

Mice (Balb/c female, 6-8 weeks of age, Harlan Labs; n=8/treatment group)were injected intraperitoneally with 50 ug/kg lipopolysaccharide (LPS; Ecoli strain 0111:B4, Sigma) suspended in sterile saline. Ninety minuteslater, mice were sedated by CO₂:O₂ inhalation and a blood sample wasobtained. Serum was separated and analyzed for TNF-alpha concentrationsby commercial ELISA assay per the manufacturer's instructions (R&DSystems, Minneapolis, Minn.).

Test compounds were administered orally at various times before LPSinjection. The compounds were dosed either as suspensions or assolutions in various vehicles or solubilizing agents.
